  1. Ch 5.1-- The Scientific Revolution Main Idea New ways of thinking led to remarkable discoveries during the Scientific Revolution.

  2. The Old View New Viewpoints 1550’s • Scholars relied on traditional authorities for beliefs of the universe • Geocentric theory, Aristotle • Earth center of universe • Sun, moon, planets revolved around sun • Ideas upheld by church, accepted authority for European intellectuals • Scientific Revolution, new way of thinking, posed theories, and developed procedures to test ideas • Why open to new ideas? • Exploration • New lands, new people, new animals Dawn of Modern Science Some Middle Ages scholars sought answers about the natural world from the church.

  3. Ancient scholars could provide no information about new lands, people, animals Age of Exploration led scientists to study natural world more closely Other things to be discovered, things unknown to ancients Navigators needed more accurate instruments, geographic knowledge Scientists examined natural world, found it did not match ancient beliefs Dawn of Modern Science

  4. Scientific Method Scholars New Approach to Investigation • Francis Bacon, experimentation to gain scientific knowledge • Rene Descartes, reason key • Believed everything should be doubted until proved by reason • Relied on math, logic • Influence modern scientific methods • The Scientific Method • Identify problem • Form hypothesis • Perform experiments to test hypothesis • Record results • Analyze results, form conclusion

  5. Discoveries in Astronomy, Physics, and Math • Early scientists • Made significant contributions in astronomy, physics and math • Copernicus • Found geocentric theory of movement of sun, moon, planets not accurate • Heliocentric theory, earth revolves around sun • Concluded sun, not earth, near center of solar system • Copernicus developed detailed mathematical explanation of process • Was first scientist to create complete model of solar system

  6. On the Revolutions of the Heavenly Spheres • Copernicus’ famous book not published until last year of his life • Knew church would oppose work • Work contradicted teachings of church • Weaknesses of theory • Mathematical formulas did not predict positions of planets well • Copernicus did not want to be ridiculed for weaknesses • Died 1543 after work published, other scientists expanded on ideas

  7. Observations Kepler, German Mathematician • Developed system to explain planetary movement • Believed sun revolved around earth • Other five known planets revolved around sun • Hired as Brahe’s assistant to form mathematical theory from measurements of planets • Published result of measurements of orbit of Mars after Brahe’s death Brahe and Kepler • Brahe, Danish Astronomer • Discovered a supernova, distant exploding star suddenly visible on earth • Book impressed Denmark’s King Frederick II • Gave Brahe money to build two observatories

  8. Brahe and Kepler Brahe’s assistant Kepler solved main problem of Copernican theory Copernicus assumed planets orbited in circle Kepler found assumption untrue Proved planets orbited in oval pattern, ellipse Wanted to prove Copernicus wrong, instead proved heliocentric theory correct Kepler’s mathematical solar system model also correct Discoveries in Astronomy, Physics, and Math Kepler, German Mathematician

  9. Discoveries in Astronomy, Physics, and Math • Galileo Galilei • Built first telescope used for astronomy • Craters on moon, sunspots • Saturn, moons of Jupiter • Milky Way made up of stars • Isaac Newton • Brought together astronomy, physics, math • Book explained law of universal gravitation • Gravity affects objects on earth, also in universe • Keeps planets in orbit

  10. Newton developed calculus, new kind of math Used calculus to predict effects of gravity German philosopher Gottfried von Leibniz also developed calculus at same time Each accused the other of plagiarism Historians believe it was simple case of independent discovery Discoveries in Astronomy, Physics, and Math

  11. Discoveries in Astronomy, Physics, and Math • Galileo’s Theories • Brought him into direct conflict with the church • Church leaders pressured him not to support ideas of Copernicus • Dialogue concerning Two Chief World Systems, 1632, showed support • Trial 1633 • Pope Urban VII ordered Galileo to Rome to stand trial before Inquisition • Church wanted to stamp out heresy, or dissenting views • House Arrest • Galileo stated would not use Copernican theory in work • Received lenient sentence in return • Pope ordered Galileo under house arrest, where he spent rest of life

  12. Vesalius William Harvey • Used bodies of executed criminals for dissection • Hired artists to produce accurate drawings • On the Workings of the Human Body, 1543 • English physician, early 1600s • Observed, explained workings of human heart • Described blood, circulatory system functions Discoveries in Biology and Chemistry Scientists used the scientific method to acquire new knowledge and make great discoveries in the fields of Biology and Chemistry.

  13. Antony van Leeuwenhoek, Dutch scientist, 1600s • Used interest in developing magnifying lens to invent microscope • First to describe appearance of bacteria, red blood cells, yeast, other microorganisms • Robert Hooke, English physician, inventor • Used early microscope to describe appearance of plants at microscopic level • Credited with creating the term cell

  14. Antoine-Laurent Lavoisier Robert Boyle • French chemist, 1700s • Developed methods for precise measurements • Discovered law of Conservation of Mass, proved matter could not be created, destroyed • Recognized, named oxygen, introduced metric system, invented first periodic table • Father of modern chemistry • First to define element • The Sceptical Chemist, 1661, described matter as cluster of tiny particles (now called atoms) • Changes in matter occurred when clusters rearranged • Boyle’s law - temperature, volume, pressure affect gases Chemistry

  15. Science and the Church Conflicts • Primary resource for knowledge, learning • Cathedral schools, universities trained people to run the church • Most scientists did not want to challenge role of Christianity • Church explained world through inspiration, revealed truth • Science explained world through logical reasoning Science and Society While the church opposed the views of many scientists, it benefited from new discoveries that made Renaissance art and architecture possible. The church feared reason as an enemy of faith, but eventually began to embrace some of the achievements of the Scientific Revolution.

  16. Science and Art • Renaissance • Study of art, architecture not separate from study of science • Artists learned anatomy in order to paint the body • Artists • Experimented with chemistry of paints, nature of light • Used math to create compositions of perfect balance • Architecture • Mathematics, physics crucial to great architecture • Also used in engineering achievements of the time • Science and religion • Combined to produce great artistic achievements of Renaissance • Most art, architecture dedicated to glory of God

  17. Scientific Revolution established new way of thinking about physical world Great advances made in astronomy, physics, biology, chemistry Advances influenced developments in arts, architecture Scientific Revolution soon would cause philosophers, scholars to wonder if reason could solve poverty, war, ignorance Science and Community Summary
